摘要： A charge completion detector comprises a thermoelectric detecting element outputting a thermally generated electromotive force in correspondence with the rise of temperature incidental to the completion of charging a secondary cell, and detecting means electrically connected to the thermoelectric detecting element for detecting the thermally generated electromotive force generated in the thermoelectric detecting element. The thermoelectric detecting element comprises a base material of semiconductive ceramics and a plurality of pairs of electrodes formed spaced apart from each other by a prescribed distance on the base material for forming hot junctions and cold junctions. A heat radiating member is thermally coupled to the cold junctions of the base material. The temperature of the hot junction side thermally coupled to the secondary cell will be approximately the same as that of the secondary cell while the temperature of the cold junction side is kept at an environmental temperature. The rise of temperature is detected based on the change of the thermally generated electromotive force based on the difference between the temperatures of the hot junctions and cold junctions.

摘要： A liquid level sensor for detecting a level of an electrolyte where: a pair of resistance films are formed on an insulating substrate: a plurality of electrodes are intermittently mounted on the resistance films in the longitudinal direction; the resistance films are soaked in the electrolyte in the vertical direction along the longitudinal direction; the liquid surface is detected from the variation of the resistance value of the resistance films caused by the short-circuiting of pairs of the electrodes in the electrolyte. The exposed surface of the resistance film is covered by a moisture-resistance film. The result is that undesirable change of resistance value of the resistance film caused by being moistened can be reliably prevented.

摘要： A vibrating gyroscope includes supporting members which are fixed in the vicinity of two node axes n1 and n2 of a bar-shaped vibrator. The supporting members corresponding to node axis n1 extend from the locations at which they are fixed to the vibrator in the widthwise direction of the vibrator, and also include bending portions and a proximity portion. The bending portions bend toward node axis n1. At the proximity portion, the supporting members are in close proximity with each other with a gap therebetween in the vicinity of node axis n1.
